signor to The W. E. Long Company, Chicago, Ill., a corporation of Illinois Application December 11, 1939, Serial No. 308,607 6 Claims. (Cl. 20S- 44) A further object of the invention is the provision of a new and improved carton in box form made from a single piece of cardboard and having reinforced corner members.

A stm further object of the invention is the provision of a new and improved carton in box form fabricated from a single piece of material and having windows in its walls.

Another object of the invention is the provision of a new and improved one-piece carton in box form and of paperboard, or board made of cellulose or the like, that is easily fabricated, inexpensive to manufacture, and that is reinforced and comparatively sturdy in construction.

Other and further objects and advantages of the invention will appear .from the following description, taken in connection with the accompanying drawings, in which- Fig. 1 is a perspective view of the carton with the top closed, and with parts broken away;

Fig. 2 is a similar view but showing the top in open position;

Fig. 3 is a section on the line 3 3 of Fig. 1;

Fig. 4 is a section on the line 4-4 of Fig. l, with parts removed; and l Fig. 5 is a plan view of the blank from which the carton is made or fabricated.

In the construction of cartons, boxes or containers, and the like, from a single piece of material, it is common practice to fashion or cut the piece in such manner that when folded to proper form and the completed carton put to its intended use, the parts subjected to the greatest strain or the parts that retain the shape or form of the carton when constructed are not properly reinforced. The present invention seeks to remedy this diiculty by providing integral reinforcing means for the vertical corners and other parts of the carton whereby the latter will retain its original shape or form.

Referring now to the drawings, the reference character 5, Fig. 5, designates the blank from which the carton is made. This blank comprises the body portion or bottom wall 6 which, in the form shown, is rectangular. The body portion 6 is provided with side extensions 1 and 3 extending laterally in opposite directions. The extension 1 is adapted to be folded along the line 9-9 to form what, for convenience of description, will be termed the side Wall III and the top section I I of the carton or container. The extension 8 is likewise adapted to be folded along the line I2-I2 to form what is destined to be the side wall I3 and the top section IIa. The body portion 6 is also provided with end extensions I4 and- I5 which extend in opposite directions to form what will be termed the ends or end walls of the carton when the same is completed.

' The end extensions I4 and I5 are severed from the extensions 1 and 8 by slits I6, I1, I8 and I9. These slits are parallel with the side extensions 1 and 8 and are along the side edges of said extensions. They are of a' depth suiiicient to form the naps 2I and 22 of the end extension I4 and the flaps 23 and 24 of the -end extension ,of the slits 25 and 26 and I8 and I9, respectively,

through for forming flaps 20 and 3 0 which form ledges across the top of the carton when the same is completed, Fig. 2. The tabs 21 and 28 of the end sectionlf I4 are folded at right angles to the plane of the ap 20 so that they will engage the flaps 2| and 22 and extend downwardly alongside the same when the carton is completed, as clearly shown in Fig. 3. The tabs 32 and 33 are likewise adapted to be folded to extend downward alongside the aps 23 and 24 to which they are adapted to be attached in the completed carton.

The side extension 1 is provided with slits 34 and 35 which are in alinement and are parallel with the end extensions I4 and I'5 and are of such depth as to form tabs 36 and 31. Ihe side extension 8 is likewise provided with the slits 38 and 38 for forming the tabs 4I and 42 on what may be termed the sectional fla-p 40.

The'v end and side extensions are adapted to be folded at right angles to the body portion 8 to frm the end and side walls of the carton. If desired, the blank may be scored along the lines 43, 44, 45 and 46 so that the 'material may be more easily folded along these lines. It will be noted that the line 43 extends through the bottoms of the slits 25, I 6, I9 and 3I and that the line 45 extends through the bottom of the slits 26, II, I8 and 29. The lines 44 and 45 are in alinement with the slits I6, II and I8, I9, `respectively, so that the parts may be properly folded to form the end and side walls and also to form the flaps on the end walls, as will presently appear.

The side extension 8 may also be scored in alinement with the slits 38 and 39 so that the flaps 40 may be more easily folded. All of the scorings may be dispensed with, if desired. One of the side extensions, as the flap on the extension 8, may be slit to form a tab 4' I which may be used in opening the container.

The -blank may be folded in various Ways to form the carton. One form will be given by way of example. I

The tabs 32 and 33 are folded at right angles to the plane of the end extension I5 along the lines 43 and 45 and then the flap 30 is folded at right angles to the blank along the line of the slits 29 and 3|. The flaps 23 and 24 are then folded at right angles to the blank along the lines 45 and 43, respectively, over into engagement with the tabs 32 and 33 and attached thereto by a paste, cement, or the like, as shown in Fig. 2 of the drawings. After both end extensions have thus been treated, they are then folded at right angles to the blank -along the lines 44 and 46.

The folding of the side extensions will now be described.

The side extension 'I is folded along the line 9--9 at a right angle to the bottom wall I I after which the side Wall I0 is folded at a right angle to the body portion 6 along the line 43 thus bringing side wall I0 into engagement with the flaps 2I and 24 to which they are fastened by cement, or the like, for forming reinforced corner members.

The side extension 8 is then folded into position. It is folded at a right angle along the line I2-I2 and the sections of the flap 40 are folded along the dotted line 10 through 180. The side wall I3 is then folded through 90 along the dotted line 45 and is secured to the flaps 22 and 23 in any suitable manner, as by means of cement, glue, or the like.

The carton is now complete, as shown in Fig. 2A, and after the product has been placed in the same, or the carton has been lled, the closure or top lwall is closed by bending the top sections to form a window in both side and top walls, as clearly shown in Fig. 1 of the drawings.

While the carton, as shown in Figs. 1 and 3, has transparencies in its walls, it is understood that this is by way of example only as it may be made otherwise.

It is thought from the foregoing, taken in connection with the accompanying drawings, that the construction of my device will be apparent to those skilled in the art and that changes in size, shape, proportion and details of construction may be made without departing from the spirit and scope of the appended claims.

I claim as my invention:
